Detection of the expression of heat shock protein 70 using quantum dots as fluorescence probe in human renal carcinoma

Objective： To detect the expression of heat shock protein 70 （HSP70） in human renal carcinoma tissues and cultured ACHN cells by using quantum dots-tagged fluorescence technology and its significance. Methods： Using the fluorescence property of quantum dots, indirect immunofluorescence method and immunocytochemical method were used to detect the expression of HSP70 tagged by quantum dots in renal carcinoma tissues and ACHN cells cultured in vitro. Results： Confocal fluorescence microscopy showed that HSP70 were significantly expressed in renal carcinoma tissues and ACHN cells cultured in vitro characterized by homogeneous distribution of intensive salmon pink fluorescence. Compared with FITC tagging, quantum dots tagged fluorescence had good specificity and signal to background. There was no notable quenching after excitation by quantum dots for 30 rain. Conclusion： Quantum dots can be used to label subcellular proteins and have obvious advantages compared with the traditional fluorescence methods. The quantum dots-tagged fluorescence could be applied as a new method for clinical labeling detection.     

Notch信号相关受体/配体在皮肤恶性黑素瘤中的表达

目的 检测Notch信号通路中Notch1、Notch4、Jagged1以及Dll4在皮肤恶性黑素瘤组织中的表达,初步探讨Notch信号通路在黑素瘤发病机制中的作用.方法 免疫组化SP法检测40例恶性黑素瘤及15例色素痣石蜡标本中Noteh1、Notch4、Jagged1以及Dll4的表达模式和表达强度.采用SPSS21.0软件进行卡方检验及Spearman秩相关分析.结果 在40例黑素瘤组织(31例阳性表达)及15例色素痣组织(3例阳性表达)Notch1的表达率差异有统计学意义(x2=15.281,P=0.000),原位(18例)及侵袭性黑素瘤(22例)间Notch1表达强度差异无统计学意义(x2=0.631,P=0.427).Notch4、Jagged1以及Dll4的表达率在恶性黑素瘤与色素痣之间差异均有统计学意义(均P＜0.05),三者表达强度在原位与侵袭性黑素瘤之间差异亦均有统计学意义(P＜0.05).在黑素瘤组织中,Notch1与Jagged1的表达呈正相关(rs=0.350,P=0.027),与Dll4的表达亦呈正相关(rs=0.562,P=0.000),但是Jagged1与Dll4的表达呈负相关(rs=-0.734,P=0.000).结论 Notch信号通路异常可能是黑素瘤的发病机制之一,但具体作用机制有待进一步研究.     

银屑病的瘙痒特征及相关因素分析

目的调查银屑病患者中瘙痒发生率、瘙痒程度等临床特征及其影响瘙痒的相关因素。方法采用问卷调查的形式调查了112例银屑病患者,评价其瘙痒特征及影响瘙痒的相关因素。结果 112例银屑病患者中83%存在不同程度瘙痒,相关分析显示:患者瘙痒与否与年龄、疾病活动度呈显著相关(P0.05),而与患者性别、病程、家族史、吸烟、饮酒及身体质量指数(BMI)无相关性,瘙痒程度与银屑病皮损面积及严重程度指数(PASI)评分、浸润程度呈显著相关(P0.05),而与红斑、鳞屑无相关性。结论大多数银屑病患者存在不同程度的瘙痒症状,年纪越大、皮损越广泛、浸润程度越高以及处在进展期的银屑病患者瘙痒越剧烈。     

The 5-year incidence of male breast cancer in Southwest of China from 2007 to 2011

Objective： Male breast cancer is a rare disease with an incidence of about 1% of breast cancers in USA, but relatively lack of the information of male breast cancer in China, especially in Southwest of China, led us to study its incidence trends. Methods： Chongqing is one of the biggest and the most important areas that is located in Southwest of China. There are around 31.4 million people who live in approximate 82 402.95 km2 area of Chongqing. Data about breast cancer patients registered in the Center for Disease Prevention and Control of Chongqing （China） were statistically collected from 187 hospi- tals, about 58 hospitals in city and 129 hospitals in country, and over 6.2 million people were studied every year. It was tried to represent all the people in villages and cities in Chongqing, China. Results： The incidence of male breast cancer in Southwest of China ranged from 0.34/100 000 to 1,45/100 000 between 2007 and 2011, while the incidence of female breast cancer ranged from 15.40/100000 to 21.66/100000 at the same time. The rate of male breast cancer to female breast cancer ranged from 0.02：1 to 0.07：1, male breast cancer accounted for 1.96% to 6.5% （with the mean value of 2.9%） of breast cancers in Southwest of China from 2007 to 2010. Conclusion： In Southwest of China male breast cancer accounts for about 2.9% of breast cancers which is higher than that in United States. It is important for policy makers and health manager to seriously consider breast cancer in future plan in Southwest of China.
